In May 2015, a fish species and fishery resources survey was carried out in the middle reaches of the Yarlung Zangbo River in Tibet, and one species suspected to be the natural hybrid of was found in the waters of Sangri and Langxian. Morphological analyses showed that the morphological characteristics of the head, including snout, mouth, jaw, and beard length, were in the middle form and distinct from . The head shape of the individuals in the population was stable and consistent, all with typical intermediate characteristics, and there was no significant difference between individuals. Barcode analysis based on the mitochondrial CO I gene showed that 4 of the 15 samples from the hybrid population were homologous with , and the genetic relationship was close to each other. This suggested that individuals with the genotype of were both present in the suspected hybrid population. In the present study, the results showed that could hybridize in natural waters to produce offspring. However, the hybrids produced by as the maternal parent were dominant in the population, and it was considered that specific environmental factors in the waters of Sangri could enhance spontaneous inter-species hybridization between .
